Health Assessment Final Flashcards
The number of muscle fibers is determined in utero we are born with the # of muscle fibers we will have for life over time the muscle fibers lengthen
When is bone growth completed and the peak bone mass achieved? Why is this important
Bone growth is completed at 20 years old but peak bone mass is achieved at 35 years old.
Having a balanced diet is essential, crash diets are bad. You are building the strength of the bones during this time esp for menopause and later years.
The balanced diet and increased calcium will decrease the chance of osteopenia, osteoporosis and fractures
How does being pregnancy affect the MS system?
Increase mobility of pelvic joint
Lordosis of spine (inward forward curvature) Waddle gait
Lower back pain
Muscle cramps
Increased fluids increase risk of carpal tunnel syndrome
How is the MS system of the older adult affected?
Alteration of the equilibrium between bone deposition and bone reabsorption results in Loss of bone density esp vertebrae and long bones
Higher risk of fx
Deterioration of joint cartilage
Decreased mobility
Muscle mass decreases
Axial Skeleton

Appendicular Skeleton

HUMAN
SKELETON
AP VIEWS

Skeletal muscles from anterior and posterior views.

Articular Structures
include joint capsule and articular cartilage, synovium and synovial fluid, intra-articular ligaments, and juxta-articular bone
Extra-articular structures:
include periarticular ligaments, tendons, bursae, muscle, fascia, bone, nerve, and overlying skin
Ligaments connect

Bone to Bone
Tendons Connect

Muscle to Bone

Synovial Joints
Freely movable
•Freely moving articulations containing ligaments and cartilage covering the ends of the opposing bones that are enclosed by a fibrous capsule
·eg: Knee, shoulder
•Synovial membranes line the joints and secrete the serous lubricating synovial fluid
MOST JOINTS ARE SYNOVIAL

Cartilaginous Joints
◦Slightly movable
◦
·eg: Vertebrae

Fibrous Joints
◦Immovable
◦
·eg: Skull sutures
Synovial Joint
Spheroidal
(ball and socket)
Type of Joint: Convex
surface in
concave cavity
Articular Shape: Wide-ranging flexion, extension, abduction, adduction, rotation, circumduction
Ex: Shoulder, hip

Synovial Joint
Hindge
Articular Joint: Flat, planar
Movement: Motion in one plane; flexion, extension
Ex: Interphalangeal joints of the hand and foot; elbow

Synovial Joints
Condylar
Articular Shape: Convex or concave
Movement: Movement of two articulating surfaces
not dissociable
Ex: Knee; temporomandibular joint
Bursae
develop in the spaces of connective tissue between tendons, ligaments, and bones to promote ease of motion at points where friction would occur
Wrist
(Radiocarpal Joint)
•Articulations of:
- •Radius and carpal bones
- •Proximal and distal row of carpal bones
- •Articular disc, ulna and carpal bones
Flexion and extension
Rotational movement
Hand
Articulation of:
- Carpals and metacarpals
- Metacarpals and proximal phalanges
- Middle and distal phalanges
Forearm
Articulation of:
- Articulations between radius and ulna at both proximal and distal locations
- Pronation and supination

Elbow
- Articulation of humerus, radius, and ulna
- Enclosed in a single synovial cavity
- Ligaments of the radius and ulna protecting the joint
- Bursa lies between olecranon and the skin
- Hinge joint permitting movement in one plane (flexion and extension)

Shoulder
(Glenohumeral joint)
- Articulation between the humerus and the glenoid fossa of scapula
- Ball-and-socket joint that permits movement of the humerus in many axes
- Acromion and coracoid processes and ligaments between them form arch surrounding and protecting joint

What are the shoulder and position of the humeral head stabilized by
Rotator cuff
What Muscles and their tendons comprise the rotator cuff
Supraspinatus
Infraspinatus
Teres minor
Subscapularis
